About flymake-flycheck about emacs.d HOT 10 CLOSED

Sorry, I didn't quite understand what's wrong here. How would I reproduce this?

I added the configuration in init-local.el.
(add-hook 'c-mode-common-hook 'eglot-ensure)
Then close all the c files, restart emacs, open C file will pop up this error.

Is my configuration incorrect?
But even if I don't use eglot. If I don't comment out the above lines (flymake-flycheck).
Opening the c project *Flymake diagnostic gives an error similar to the following:
The test project is xv6-riscv

1 9 error ( 'kernel/types.h' file not found [c/c++-clang]

I found that the value of flymake-diagnostic-functions is different
flymake-check does not open:

Its value is (eglot-flymake-backend)

When flymake-check is on:

Its value is
(eglot-flymake-backend #f(compiled-function
                          (report-fn &rest _)
                          #<bytecode 0x5319205130afeb4>))

from emacs.d.

Yeah, I guess it's possible that if some flycheck backends are enabled, then they will be used via flymake-flycheck alongside eglot. I'll have a think about how to tackle this. In the meantime you can probably add unwanted flycheck backends to flycheck-disabled-checkers.

It's very effective. Thank you for your help.

 (setq-default flycheck-disabled-checkers
                  (append (default-value 'flycheck-disabled-checkers)
                          '(c/c++-clang c/c++-gcc c/c++-cppcheck)))

Thanks for confirming that this helped you!

I also want to disable c/c++-clang and enable eglot-flymake-backend. I tried to put in init-local.el

(with-eval-after-load 'flycheck (add-to-list 'flycheck-disabled-checkers 'c/c++-clang))

as suggested in the link.

However, it does not work unless I delete (add-hook 'flymake-mode-hook 'flymake-flycheck-auto) in init-flymake.el and add it after (add-to-list 'flycheck-disabled-checkers 'c/c++-clang) in init-local.el.

I wonder if there is any way to reconcile without modifying anything in init-flymake.el. I want to keep things synchronized with you and avoid corruption from my changes.

Another things is that after I disable c/c++-clang in a dirty way, the backend eglot-flymake-backend cannot be enabled automatically. Executing M-x flymake-running-backends gives me nothing. I have to execute M-X eglot in the buffer manually and eglot checker got invoked. Is there suggestions to overcome this step and make things consistent with flymake-flycheck?

Many thanks!

Edited: It is not necessary to invoke

(add-hook 'flymake-diagnostics-functions 'eglot-flymake-backend nil t)

instead, I have to do

(add-hook 'c++-ts-mode-hook 'eglot-ensure)
(add-hook 'c++-mode-hook 'eglot-ensure)

from emacs.d.

@yszhang95 Thanks for the info. What do you mean by "the backend eglot-flymake-backend cannot be enabled automatically"? Do you mean when eglot is active in a project, and you open a new buffer, for example? I'm interested in how to reproduce this issue step-by-step specifically, because I'd like to fix it.

Thank you for the quick reply @purcell !

When I tried to prepare for a minimal example to reproduce, I found I have to include

(add-hook 'c++-ts-mode-hook 'eglot-ensure)
(add-hook 'c++-mode-hook 'eglot-ensure)

Sorry for the misleading question. I will update my last comment to avoid misleading others.

The remaining question is the first one, how to avoid corrupting your setup.

Best regards!
